钯硫酸钡催化剂PD/BASO4 - Introduction
Sponge Palladium is a porous solid material with Palladium as the main component, which has the following properties and uses:
Nature:
1. Porosity: Sponge Palladium has a high specific surface area and porosity, which can provide a larger reaction surface area and is conducive to catalytic reactions.
2. High catalytic activity: sponge Palladium has excellent catalytic activity, especially suitable for gas phase catalytic reaction.
3. High temperature resistance: sponge palladium can maintain stable performance at high temperature.
Use:
1. Catalyst: Sponge palladium is widely used as a catalyst in chemical reactions, especially in gas phase reactions, such as organic synthesis, redox reactions and hydrogenation reactions.
2. Automobile catalyst: sponge palladium is often used in automobile exhaust gas treatment devices to catalytically convert harmful gases (such as CO, NOx, etc.) into harmless substances.
3. Electrochemistry: Sponge palladium can also be used in the fields of hydrogen production by electrolysis of water, electrochemical synthesis and capacitors.
Preparation Method:
Sponge Palladium preparation methods are varied, common methods include:
1. Chemical hydrogen evolution method: Palladium Salt is reacted with reducing agent, and sponge palladium is prepared by hydrogen evolution reaction.
2. Template method: metal palladium is deposited on the surface of the template, and then sponge palladium is obtained by removing the template.
Safety Information:
1. Sponge palladium is relatively stable at room temperature, but oxidation reaction may occur at high temperature, so it is necessary to avoid high temperature and oxygen environment.
2. Palladium is a precious metal, need to pay attention to prevent waste and avoid excessive use.
3. Sponge Palladium powder can form a cloud of flammable particles in the air, should avoid fire and violent friction.
4. When using sponge palladium, pay attention to avoid inhalation of dust and skin contact, wear protective gloves and masks. In case of accidental contact, flush with plenty of water and seek professional medical help.
